PLOW.

SPECIFICATION forming part of Letters'Patent No. 231,778, dated August 31, 1880.

Application filed February 14, 1880. 1

To all whom it may concern:

Be it known that I, JOSEPH ELOOGK, a citizen of the United States, residing at Mechanicsburg, county of Cumberland, and State of Pennsylvania, have invented new and useful Improvements in Plows, of which the following is a specification.

The object of'my invention is to produce a strong, light, and well-braced plow; and to this end it consists in certain combinations and arrangements of devices, which will be here inafter particularly described, and pointed out in the claim.

In the accompanying drawings, Figure l is a side elevation of the furrow side of a plow constructed after the manner of my invention; Fig. 2, a similar view of the land side of the same; Fig. 3, a perspective view of the moldboard detached, looking upon its under side; Fig. 3 a similar view of the share, looking upon the upper side, showing its joining surface with the under side of Fig. 3; Fig. 4,a perspective view of the upper plate for attachment of colter and bolts of plowsharc; Fig. 5, a sideview of the upper end of colter-blade, with its securingbolts in section and clamping-plate shown in dotted lines Fig. 6, a perspective view of the slotted knee-plate detached, which connects the landside handle adjustably with the beam Fig. 7 a plan view of theclevis with a twist-link in place, and showing its mode of attachment to the nose of the plow-beam.

The plowshare A, point A, and sole A are formed in a singlepiece, which is secured to the under surface of mold-board B by three screws, (1 a a, passing through it into the mold-board, and is additionally secured to themold-board and plow-beam by a through-bolt, as will hereinafter appear. The landside of the mold board is faced with two fiat plates, 0 0, secured to it by suitable screws or bolts, one of which plates, 0, is formed of steel and extends to and overlaps the front edge of the moldboard and forms the shin or cutting-edge. The point of the share slopes from the land side to the furrow side, and from its tip to its point of connection with the mold-board. The face of the share is sloped at a vertical angle of about twenty degrees, and the face of the forty-five degrees, and the cutting-edge of the share and lower part of the mold-boardare formed at an angle of about thirty six degrees with the landside edge, and a horizontal section through the upper portion of mold-board gives an angle of about forty to forty-five degrees with the surface of the ground. The face of the mold-board is nearly straight at its front edge or shin for two-thirds of its height, and then turns abruptly outward at its throat, and is slightly dished toward its upper rear edges.

By the peculiar shape of the point and face of the share the furrow-slice is turned nearly half over before it reaches the mold-board.

The heel A of the share is of rectangular shape and projects back to the rear end of the landside, and forms a ledge upon which the landside-plates rest, so that their outer surfaces are all flush with each other.

The plowshare, mold-board, and their connections are secured to the beam D by a bolt, E, which passes through the beam, thence through thejupper web, I), of the mold-board, following the inner surface of the nose of the mold-board down through its lower web, and finally through the sole-plate A of the share, Fig. 3, thus securely binding the said parts together by a nut at each of its ends.

The mold-board is additionally secured to the beam D by a short bolt, F, passing through its upper web, the lower end of which passes through an eyebolt, G, that extends backward therefrom and passes through the landside-handle H, and serves to brace it firmly against the rear end of the plow-beam.

The lower end of the plow-handle H rests against and may be secured to the inner surface of the landside-plate G, and is furthermore secured adjustably to the end of the plowbeam by means of a slotted knee-plate, I, secured to it by a countersunk bolt, and which is, in turn, clamped to the rear end of the beam by a clamping-bolt, -i, and nut, which passes through the bolt and also through the slot t" of the plate, so that the beam may be shifted to suit the line of draft.

The knee-plate is provided with a flange, i, which overlaps the inner side of the plowhandle H, and is thereby more securely atmold-board joins it atavertical angle of about tached to it. The other handle, H, of the plowis secured to the inner surface of the moldboard and connected with its fellow handle by suitable rounds in a well-known manner.

The colter K is attached to the beam in the following manner: A cap or plate, L, is secured to the upper surface of the plow-beam, directly above the point of attachment of the moldboard, share, &c., by the same bolts, E F, which secure the mold-board and its connections to the beam, and also forms a bearing and clamping-plate above the beam to aid in holding the parts above named more securely together. This plate L is provided with a bolt-hole crossing the beam, and is made square a sufficient distance to hold a square shank on the bolt 1, that passes through it to prevent said bolt from turning. A plate, M, is attached tothe under side of the beam below and slightly in advance of the front end of the plate L, and is also provided with a lateral bolt-hole similar to the one in the upper plate, but so that its bolt m will be slightly in advance of the bolt 5 in the upper plate. The colter K is placed between these bolts Zm, and is thrown in an angular position in front of and nearly parallel with the cutting-edge of the mold-board. The upper edge of the colter is notched at k to receive the bolt 1 and prevent its slipping, and is firmly clamped against the side of the beam by the plate K, through the ends of which the bolts pass and are held by clamping-nuts. By this means the colter is firmly secured to the plowbeam, and may be readily loosened and withdrawn from the beam should it become choked up with weeds and grass.

The clevis N is a stirrup-shaped piece of metal provided with a serrated platearranged longitudinally on the end or nose of the plowbeam, into which serration fits the twist-link n, for connecting the plow-beam with the open rin g of the double-tree.

The points of the serrations are so near to the end of the plow that the link cannot be moved from one notch to the other without removing the bolts which attach the clevis to the plow-beam. There are two of these bolts, one of which, N, is provided with a head and nut, and the other, N is screwed through the beam and strap of clevis, and is provided with a crank-handle for turning it. the clevis are thus securely held to the sides of thebeam,and-the serrated end plate is held The straps of in -a horizontal position, so that the draft-link may be attached to one side or other of the beam to shift the line of draft relatively to the share and cause it to take more or less land. The adjustment of the rear end of the beam with the knee-plate of the handle serves to shift the beam when the link is moved in the clevis to keep the line of draft at all times parallel with the face of the land side of the mold-board.

' A draft-plate, 0, is secured to the under side of the beam, and is held in place by suitable wood screws and bolts passing into or through the beam. The draft-plate extends from the point of connection of the share and its parts with the beam to the forward end or nose of the beam. The said plate is interposed between the beam aud upper end of mold-board throat, so that the bolts E F pass through it and are connected by it with the nose of the plow, and receives a great part of the draft, thus materially relieving the beam. The plate 0 also passes under and around the lower colter-plate, M, and securely holds it in position, so that the beam is not weakened by additional bolt-holes.

I claim as my invention and desire to secure by Letters Patent- The combination, with the mold-board formed with a web, I), uniting the mold-board with the landside, of the plow-beam, a draft-plate having its rear end interposed between said web and the underside of the beam, astrengthening plate or casting, L, receiving and holding a bolt, l, of the colter guard or holder K and applied to the upper side of thebeam, and the two bolts E and F passing through the plate L, plow-beam, draft-plate, and colterweb, the first-named bolt being extended down into the sole of the plowshare and the latternamed bolt being connected with a brace-rod extended back to the landside handle of the plow all of said members being constructed and organized substantially as herein setforth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

JOSEPH ELGOOK.
